UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 269,317, dated December19, 1882. Application filed September 2, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN G. PEACE, of Salem, in the county of Dent andState of Missouri, have invented a certain new and useful .Improvementin Umbrellas, of which the following is a specification, reference beinghad to the accompanying drawings, forming part of the same.

Figure lis an under perspective view. Fig. 2is an axial section. Fig. 3is a detail section at 3 3, Fig. 2, enlarged.

My improvement consists of an umbrella whose ribs consist of collapsibletubes of rub- Y ber cloth or other suitable material impervious to air.In the form shown and described the inner ends of the tubes communicatewith a central chamber, through which-a tubular staff or handle passes,at whose lower end is a force-pump, by which air is forced through thehandle into the chamber and the ribs to expand the umbrella.

The umbrella-cover may be of rubber cloth, or ot' any other suitablematerial secured to the ribs in any suitable way.

A is the stad, made of a number of tubular sections, c, tted togetherwith air-tightjoints. Thus an air-tight tube is formed that may be takenapart when it is desired to fold up the umbrella ina small compass.

B is a plunger, oftubular construction, working in the tubular handle A.

a is a rubber or other packing-ring, preventing the escape of airbetween the plunger B and cylindrical handle A.v

B is a knob by which the plunger B is operated, the knob having anair-passage, b', in communication with the bore of the plunger, to admitair to the same.

b is a ball-valve at the upper or inner end ot' the plunger, openinginward.

a2 is a check-valve in the cylindrical handle A', to prevent the escapeof air from the interior of the staff. The valve c2, like b, is shown ofball form, it being proposed to use rubber balls for the valves 5l butother forms of valves may be used.

The staff passes centrally through a chamber, C, made of rubber cloth orother lexible material impervious to the air. This chamber is in form ofa double convex lens. The staft passes through the Walls of the chamberwith air-tightjoints. I show the cloth turned out in short nipples c,embracing the statt, and secured by encircling ties c', of wire orcord.The

ties may be hidden by collars, one of which is shown at c2. The upperend of the statt' is closed to prevent the escape of air. The part ofthe stad' within the chamber O has perforations a3, through which airmay enter or leave the chamber.

D are ribs extending radially from the edge of the chamber. These ribsare tubular and made preferably tapering toward the outer end, the innerportions requiring more rigidity than the outer. ribs are closed,andtheir inner ends communicate with the'interor of the chamber C, sothat the inflation of the chamber causes the inliationof the ribs andcauses them to stand cover E.

The cover E may be made of any materialin common use for umbrellas,secured to the ribs in any suitable manner.

When it is desired to fold or roll up the umbrella the. sections a ofthe stai` are taken apart, which allows the escape ofthe air from thechamber C and ribs D, andthe whole may be folded into a parcel of verysmall bulk.

V'I claim as my inventionl. An umbrella having tubular ribs made ofrubber cloth or equivalent flexible material.

2. An umbrella having tubular ribs, substantially as set forth, and acentral collapsible air-chamber in communication with the ribs,substantially as set forth.

3. An umbrella having tubular ribs, a central air-chamber in connectiontherewith, and a tubular sta connected to and in communication with thesaid air-chamber.

4. In combination with the tubular ribs D, air-chamber O, and statt' A,the force -pump A B, for the purpose set forth.
